King Oddball

In King Oddball Ends The World, the player controls a floating rock head of unknown origin. The King swings a large boulder back and forth by his tongue, and the player releases the boulder by tapping the screen. The goal is to crush all tanks, helicopters and soldiers on screen with a limited amount of boulders. To achieve this, the player has to figure out how the boulder will bounce and roll as impacts and explosions affect it.
